ok, so SWIM had massively orange/red/brown naphtha which swim knew was bad news. But unwilling to throw it out (duh) SWIM put it in the freezer, and impatient as she is, kept peeking in. After about 20 minutes the naphtha had kind of cleared up a bit - it was cloudy and brown after about 10 min - and a sediment had settled. SWIM took the naphtha out and poured it through a filter into a new jar. This had to be done fast, otherwise the sediment started going back into the solvent. SWIM actually had to refreeze it for a few minutes in between because the filter in the funnel was taking so long to pass the solvent.
Then the slightly discolored naphtha went back into the freezer while the sediment was left to dry. The process was done one more time with the freezing naphtha to clean it up until it was kind of yellowish, which swim decided was a good color and would let fp.
The dried goo then underwent a washing with IPA which should, I think, collect whatever free base might be in it, but not solve the icky gooey stuff. The IPA is still evapping from the different jars and the slightly yellow naphtha yielded a bunch of faintly yellow crystals and some snow white ones. If SWIM reXs they will probably be white all the way, but who knows, maybe they're fine the way they are now. SWIM has tried to separate the white from the darker ones and is reXing the non-pure ones.
I can't say anything about yield, because after pull 3 SWIMs glass broke: the bottom just came off. So my guess is this was due to the caustic soda weakening the glass, or it could have been pressure built up from the naphtha evapping inside. In any case it was not very funny for SWIM to clean up the mess of lye+jurema tar- next time SWIM will go for PP or HDPE containers (the ones that are supposed to withstand NaOH) - and none of it could be saved. Perhaps, SWIM's intentions are not in agreement with the cosmos

or she is just being a dumbass for mixing it in glass in the first place.
In any case I thought this may be interesting for those of you who are having trouble with red naphtha as this seems to be an easy way to clean it up pretty well and probably not loose too much product.
cheers
